May 11, 2010· Bulk density of fly ash athomas236 (Mechanical) (OP) 5 May 10 06:42. Hello, Can anyone tell me which ASTM coade is most appropriate for measuring the bulk density of flyash from the combustion of coal in power station boilers. I have looked in the ASTM year book and searched this forum but found nothing.
Moisture-Density Relationship: Fly ash has a relatively low compacted density, thereby reducing the applied loading and resultant settlement to the supporting subgrade. Conditioned fly ash tailgated over the slope of an embankment can have a loose dry density as low as 650 to 810 kg/m 3 (40 to 50 lb/ft 3 ).

Density classification of an ash is a useful technique in optical characterization because the optical properties (more specifically, the complex refractive index) of a fly ash particle depend on its composition, and since density and composition are correlated, this technique helps in detecting the distribution of infrared-active oxides such as Fe,O,.
Fly ash is a common term for the final product of coal after combustion. The white ash has properties similar to portlan cement. Since portlan cement is a comon binder in conc … rete it has a multitude of construction applications. The way you can earn wealth from Fly ash is to sell the ash too the concrete market.
The fly ash produced from the burning of pulverized coal in a coal-fired boiler is a fine-grained, powdery particulate material that is carried off in the flue gas and usually collected from the flue gas by means of electrostatic precipitators, baghouses, or mechanical collection devices such as ...
